Couldn't hurt to clean the Mass Air Flow sensor... sounds kinda dumb, but coming from someone who had a 2002 Bonneville with 270,000 (that's correct) miles on it, its cheap to do, and couldn't hurt. be sure to read the directions though. fuel filter is cheap n easy to replace also.

I got a 200 dodge caravan 3.3 it will run for 10 to 20 mi then stop and wot run


You need to test for spark at a plug wire , coil , distributor etc... That sounds very much like an ignition module or crank sensor going bad. If when it dies after 10 to 20 min. an won't start pull a plug wire an have someone try to start the vehicle while you hold plug wire end near ground ,to look for spark . If there is spark , check fuel pressure . Fuel pump could be going out , fuel pump relay etc...

94 3000gt problems


Could be such a multitude of things.Good news is for that problem 90% chance it is very minor but usually not cheap(small sensors cost a lot).You have to take it to an auto parts store for a FREE diagnostic check. Takes 5 min. and will tell you what sensor,ECU etc... is bad and would cause your particular problem.Spend your $ ONLY on what is causing your actual problem and if another part checks out bad but is causing no problem do not waste your $ on replacing it.BE WISE BEWARE and use common sense.

Start great runs 10 min. Dies will not start again


It sounds like a clogged fuel filter. Can you tell me about the vehicles history? The more information the better. When was the last tune-up. Were there any resent repairs performed? Have you done any tests? Like a fuel line pressure test? anything small that you may have noticed while looking over the engine and/or the rest of the car? I hope this helps, Please let me know if you have more details or questions.

Runs then dies after about 10-20 miles, sits for while starts again runs then dies


well it is a fuel problem or electrical , If it was fuel then the filter is plugged up, on the other hand if is is eletrical it could be a bad coil

Will be driving along and the RPM's drop and it dies. Will not start, turns over but does not start. If it sits for 20 min or so it will start and run for just a bit then die again. I had the fuel pump...


ignition module is a more likely culprit. its called heat saturation. once it cools for a spell it works again. the other possibility is the crank position sensor. happy holidays

88 Toyota Corolla backfires through carburetor.


If that is carbureted, and has a mechanical fuel pump, try running a length of fuel line from inlet side of pump to a gas can that has fresh, clean fuel, and if it runs good that way, you know problem is most likely in the tank. Removing the tank & cleaning it out is best solution from there. I'd even be tempted to add a small bottle or 2 of Lucas Fuel Sytem Cleaner to first fill in clean tank, just to help clean lines as well as carb.
